The Turin giants start their quest for a ninth consecutive title in Parma on Saturday but could be without Sarri on the bench after the 60-year-old was diagnosed with pneumonia on Monday.
Sarri returns to Italy after one turbulent season in the Premier League with Chelsea, having previously coached his hometown team Napoli for three seasons.
Chain-smoking Sarri’s appointment, in place of the clean cut Massimiliano Allegri who had delivered the last five of their Serie A titles, is a break in tradition for Juventus.
But after also ditching their iconic black and white striped jersey last season, the club are looking for a change in direction. Place bet on today’s games on NaijaBet 24/7
Despite their success Juventus have often been criticised for their boring defensive style of play.
Club bosses want a more attractive eye-catching style of football in an attempt to increase their fan base outside of Italy.
While Sarri’s only major title was the Europa League last season with Chelsea, he promises to give serial Italian champions Juventus a more dynamic style of play.
Goalkeeper Gianluigi Buffon, returning to Turin after a season at Paris Saint-Germain, thinks the change of direction can pay off.
“Sarri is not a revolution, nor a gamble. He simply represents an untested path, a whole other story.”
Among Juventus’s rivals this season will be Carlo Ancelotti’s Napoli and Inter Milan, now coached by former Juventus boss Antonio Conte.
But Juventus have spent big giving Sarri a stellar squad to target a 36th Scudetto and their first Champions League title since 1996.
Cristiano Ronaldo, a player who Sarri insists “will make the difference”, will again be central to attack with newly-signed Dutch star Matthijs De Ligt the jewel in defense alongside veterans Giorgio Chiellini and Leonardo Bonucci.
De Ligt’s Ajax sent Juventus crashing out of the Champions League last season.
For Juventus sporting director Fabio Paratici all the pieces are in place for Sarri to deliver another style of football.
“We’re very happy with what has been done. We bought de Ligt, who all the top teams wanted,” said Paratici.
“Juve has very high-level players in all departments, a squad of absolute value.”
Juventus will be hoping these players and their new coach can implement the ‘Sarriball’ football philosophy: a fast-paced attacking style, that impressed during his time with Napoli.
Brazilian left-back Alex Sandro insisted Sarri was already having an impact.
“We all still have to improve naturally, but we are on the right path.”
De Ligt also praised Sarri.
“He was one of the reasons that I wanted to join here, I’ve heard a lot of good things about him and I like his footballing philosophy and how he prepares his defence.”
“I arrive surrounded by sceptics, but then I always am. I had the same at Empoli, Napoli and Chelsea.
“In football, I know only one way of removing scepticism from the minds of people: by winning convincingly.
“I haven’t won a lot, but I believe that having fun on the pitch doesn’t stop you winning.”
